Download or read book Ecology of Blue winged Teal Wintering in the Neotropics written by Jorge Eduardo Botero and published by . This book was released on 1992 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 30 species of North American waterfowl winter in the Neotropics, with distributions that extend south of the United States into Mexico, Central America, South America, or the Caribbean islands. Leopold (1959) suggested that 9-17% of the total North American waterfowl population crosses the U.S.-Mexico border during migration. Saunders and Saunders (1981) reported sizable numbers of northern shoveler (Anas clypeata), gadwall (A. strepera), northern pintail (A.acuta), green-winged (A. crecca), and redheads (Aythya americana)wintering in Mexico. Bellrose (1980) suggested that the majority of black brant (Branta bernicla), blue-winged teal (Anas discors), and cinnamon teal (A. cyanoptera) winter south of the United States.

Available in PDF, EPUB and Kindle. Book excerpt: The best-selling and authoritative reference book on waterfowl has been fully revised and updated by one of the world’s most respected waterfowl biologists. Honorable Mention for the PROSE Award for Excellence, Multivolume/Science of the Association of American Publishers Ducks, Geese, and Swans of North America has been hailed as a classic since the first edition was published in 1942. A must-have for professional biologists, birders, waterfowl hunters, decoy collectors, and wildlife managers, this fully revised and updated edition provides definitive information on the continent's forty-six species. Maps of both winter and breeding ranges are presented with stunning images by top waterfowl photographers and the acclaimed original artwork of Robert W. (Bob) Hines. Originally authored by F. H. Kortright and later revised by Frank Bellrose, this latest edition, which has been meticulously updated by renowned waterfowl biologist Guy Baldassarre, continues the legacy of esteemed authors. Each species account contains in-depth sections on: • identification • distribution • migration behavior • habitat • population status • breeding biology • rearing of young • recruitment and survival • food habits and feeding ecology • molts and plumages • conservation and management To facilitate identification, the species accounts also include detailed illustrations of wings. An appendix contains comparative illustrations of ducklings, goslings, and cygnets. This edition of Ducks, Geese, and Swans consists of two volumes, printed in full color, and packaged in a slipcase, along with a CD containing references and additional maps.
Download or read book Emergent Ecologies written by Eben Kirksey and published by Duke University Press. This book was released on 2015-11-27 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an era of global warming, natural disasters, endangered species, and devastating pollution, contemporary writing on the environment largely focuses on doomsday scenarios. Eben Kirksey suggests we reject such apocalyptic thinking and instead find possibilities in the wreckage of ongoing disasters, as symbiotic associations of opportunistic plants, animals, and microbes are flourishing in unexpected places. Emergent Ecologies uses artwork and contemporary philosophy to illustrate hopeful opportunities and reframe key problems in conservation biology such as invasive species, extinction, environmental management, and reforestation. Following the flight of capital and nomadic forms of life—through fragmented landscapes of Panama, Costa Rica, and the United States—Kirksey explores how chance encounters, historical accidents, and parasitic invasions have shaped present and future multispecies communities. New generations of thinkers and tinkerers are learning how to care for emergent ecological assemblages—involving frogs, fungal pathogens, ants, monkeys, people, and plants—by seeding them, nurturing them, protecting them, and ultimately letting go.

Download or read book Texas Waterfowl written by William P. Johnson and published by Texas A&M University Press. This book was released on 2013-01-18 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this beautifully illustrated guide, two practicing wildlife biologists describe the life histories of forty-five species of ducks, geese, and swans that occur in Texas. For common species and those that breed in the state, each account begins with an interesting fact (such as, “Red-breasted Mergansers have been clocked at over 80 mph, the fastest recorded flight speed for a duck . . .”) and provides information on Texas distribution and harvest, population status, diet, range and habitats, reproduction, and appearance. Exquisite photographs, informative distribution maps, and a helpful source list accompany the species descriptions, and the book offers a glossary and full bibliography for those who want to explore the literature further. With the degradation and disappearance of the inland and coastal habitats that these birds depend upon, the natural history of these waterfowl species provides a vital reminder of the interconnectedness and crucial importance of all wetlands. Birders, biologists, landowners, hunters, outdoor enthusiasts, and all those interested in the health and preservation of our coastal and inland wetland resources will enjoy and learn from this book.

Download or read book The North American Perching and Dabbling Ducks written by Paul Johnsgard and published by Lulu.com. This book was released on 2017-03 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, the fourth in a series of books that collectively update and expand P.A. Johnsgard's 1975 The Waterfowl of North America, summarizes research findings on this economically and ecologically important group of waterfowl. The volume includes the mostly tropical perching duck tribe Cairinini, of which two species, the muscovy duck and the wood duck, are representatives. Both species are adapted for foraging on the water surface, mostly on plant materials, but typically perch in trees and nest in elevated tree cavities or other elevated recesses. This volume also includes the dabbling, or surface-feeding, duck tribe Anatini, a large assemblage of duck species that mainly forage on the water surface but nest on the ground, or only very rarely in elevated locations. Of this tribe, 12 species that regularly breed in North America are included, among them such familiar species as mallards, wigeons, pintails, and teal. Descriptive accounts of the distributions, populations, ecologies, social-sexual behaviors, and breeding biology of all these species are provided, together with distribution maps. Five additional Eurasian and West Indian species have been reported several times in North America; these have been included with more abbreviated accounts, but all 17 species are illustrated by drawings, photographs, or both. The text includes about 84,000 words and contains more than 1,000 references. There are also 12 distribution maps, 21 drawings, 28 photographic plates, and 58 anatomical or behavioral sketches.
Download or read book Wildlife Ecology and Management in Mexico written by Raul Valdez and published by Texas A&M University Press. This book was released on 2019-02-07 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico is the fourteenth largest country in the world and ranks fifth in biodiversity. Located in the transition zone between the temperate and tropical regions of North and South America, Mexico is an important migratory corridor for wildlife and also provides wintering habitat for several species of bats, monarch butterflies, and temperate North American nesting birds. Mexico faces several challenges to wildlife management and conservation efforts. While there is increased public education and acknowledgment of the valuable benefits wildlife provides, there is still much work to do to incentivize conservation efforts. Fortunately, there is growing recognition that Mexico’s wildlife resources can be a critical component in the rural economic development of the country. Bringing together an international team of wildlife experts across North America, Wildlife Ecology and Management in Mexico provides information on the status, distribution, ecological relationships, and habitat requirements and management of the most important game birds and mammals in Mexico. It also reviews current threats and challenges facing wildlife conservation as well as strategies for resolving these issues. This reference is a valuable tool for wildlife biologists, wildlife management professionals, and anyone interested in conserving Mexico’s wealth of natural resources. By laying out the challenges to conservation research, editors Raul Valdez and J. Alfonso Ortega-S. hope to encourage interdisciplinary communication and collaboration across borders.
